Japanese soccer is taking steps to keep organized crime out of the sport to avoid the fate of its South Korean counterpart.

J-League clubs, players and referees have issued a declaration in Tokyo saying they will take measures to keep anti-social elements out of the sport.

The J-League has set up a third-party hotline for anyone associated with Japanese professional soccer who wants or needs advice in dealing with suspect people.

The Japan Football Association has also contracted with the Zurich-based Early Warning System GmbH, which monitors the worldwide sports betting market.

Last year, South Korea's soccer league was hit by a massive match-fixing scandal, with nearly 80 players and brokers convicted.
